Description

[Detailed description of the invention] In order to shorten the overall length of the machine while ensuring a sufficient amount of seedlings to be placed on the seedling stand, the present invention has been designed to reduce the amount of seedlings that are supplied to the seedling stand in front of the seedling stand. This invention relates to the structure of a driver's seat for a riding rice transplanter, in which a driver's seat with childcare support is provided near the driver's seat.

Generally, rice transplanters avoid replenishing seedlings in the center of the field in order to streamline the work of replenishing seedlings to the seedling table.
A method is used to replenish the aircraft when it moves to a ridge.

As a result, a considerable amount of seedlings are left on the seedling tray, and it is sometimes necessary to replenish the seedlings.
In such a case, the front part of the seedlings that have been replenished on the seedling tray will protrude further forward than the seedling tray, and this protruding portion of the seedlings will hit the child rearing pad in the driver's seat, and the seedling tray will When the seedlings are moved laterally, the seedlings slide against the seedlings, resulting in damage to the seedlings such as the top of the bed collapsing and the stems and leaves breaking.

In view of this, the present invention has been developed to prevent damage to seedlings due to rearing and contact with the seedlings and sliding movement when the seedlings are placed with the seedlings sticking out from the front, by simply adjusting the driver's seat. It has a purpose in its completeness.

The structure of the driver's seat of the riding rice transplanter according to the present invention is the structure explained at the beginning, and is characterized in that the childcare tray can be folded forward to a position where it is retracted below the top surface of the seat. shall be.

That is, according to the present invention, when it is necessary to replenish seedlings with some of them protruding in front of the seedling stand,
By folding the nursery tray of the driver's seat forward, damage to the seedlings can be prevented by avoiding contact between the nursery tray and the protruding ridge and sliding contact between the two as the seedling tray moves laterally.

In addition, the rearing pads are retracted below the top surface of the seat when folded, so even when planting rice in such conditions, the driver can sit and drive comfortably without being hindered by the rearing pads. I was able to do it.

Hereinafter, an embodiment of the present invention will be described based on the drawings. An engine 4 and a forward-tilting seedling stand IA are reciprocated in the lateral direction before and after a pair of left and right running wheels 3, 3. Plant 4 plants between the seedling outlet at the bottom of IA and the mud surface using nail I.
By cyclically operating the seedlings B..., the placed seedlings are taken out and planted one layer at a time.For four-row planting, the device 1 and the distribution device are placed, and the seedling stand 1A is arranged. In front of this, the end (upper end) on the side that feeds seedlings to this seedling stand IA.
The driver's seat 2 is arranged nearby, and the planting is carried out using a rear float 5 that touches the mud surface when traveling and supports the aircraft with the wheels 3, 3, and a rear float 5 that touches the mud surface when the aircraft turns. A riding rice transplanter is provided with a front float 6 that supports the body with the wheels 3, 3 in a state where the rear float 5 is floated,
The driver's seat 2 has a seat 2B whose center part bulges slightly upward when viewed from the front, and a seat 2B having a shape that swells slightly upward in the center when viewed from the front, and a portal-shaped child support 2A made of a pipe when viewed from the front. / is attached to both left and right sides of the rear end of the seat 2B at the lower end.

The gate-shaped childcare support 2A is attached to the seat 2B so that the inclination angle with respect to the upper surface of the seat 2B, that is, the backrest angle, can be adjusted by swinging back and forth using the part as a fulcrum R. Left and right support portions 2a'.

By making the length H of 2a' larger than the distance I from the fulcrum R to the front end of the seat 2B, the left and right support portions 2a'
, 2a' and the upper connecting rod 2a, that is, the entire seat 2B can be swung forward and folded to a state where it is retracted below the upper surface of the seat 2B.

Is 7 in the diagram the pair of left and right grips? a,? It is a steering handle equipped with manual levers 8, 8 for operating the steering clutch near a, and this is installed so that it is lowered lower than the engine hood 9 by swinging with the base end as a fulcrum R'. It can be switched to the retracted position.

FIG. 3 shows the backrest 2A when the length H of the left and right support portions 2a/, 2a/ of the pipe portal-shaped childcare support 2A is smaller than the distance 1 from the fulcrum R to the front end of the seat 2B.
Another embodiment is shown in which the seat 2B is provided with a recess 2b into which the upper connecting rod 2a of the backrest 2A is inserted in the forward folded state in order to enable the seat 2B to be folded forward.

In this case, the backrest 2A can be configured to be foldable forward regardless of the height of the backrest 2A or the front and rear sides of the seat 2B.

In any of the above configurations, if the seedlings placed on the seedling stand IA protrude forward from the seedling stand 1A, the backrest 2
By folding A forward, it is possible to prevent the backrest 2A from coming into contact with the protruding seedlings.
